WH (Heeres) 'Nachschub'-related item: a semi-official, commemorative key-holder (aka: 'Url') depicting a (tiny) 'cyphered' shoulderstrap and chromed stirrup

This is an attractive - and actually quite scarcely found! - WH (Heeres) I deem 'Nachschub-Truppen'- (ie. transport-troops-) related item: a semi-official, commemorative key-holder (aka: 'Url') depicting a (tiny) 'cyphered' shoulderstrap and chromed steel-based stirrup and that comes in an overall very nice- (albeit clearly used- ie. worn-), condition. The detailed piece (having an approximate length (with stirrup and attachment) of 13 cms. comes mounted onto its period 'musketon'-hook (as can be noticed on the pictures). The detailed piece shows a (tiny) 'cyphered' shoulderstrap that shows the light-blue-toned piping and that has a silver-toned '2'-numeral (ie. 'Ziffer') and two pips attached is for the rest constructed from silverish-toned 'Buntmetall'-based metal and shows most of its 'silverish-like' finish: it has really nice and/or pronounced detail. I know that these desirable 'semi-official'-pieces are also copied: this is naturally a genuine example that was never before part of a collection and originates from a German-household where it was recently uncovered. In any case is this a very attractive - and without doubt scarcely seen! - 'Nachschub-Truppen'-related item!
